Title: Start control method in opposed spindle lathe
Inventor: KATO CHOJI
IPC: B23B3/30
Filed: 1987-06-23
Abstract: PURPOSE: To prevent excessive torsional torque from acting on a workpiece by constituting a lathe, when it starts two spindle driving motors, self holding one of the motors while applying predetermined torque to the other further, in that condition, releasing the one of the motors from its self holding and applying predetermined torque to this motor.  
     CONSTITUTION: When spindle driving motors 5, 6 are started in a condition that a lathe holds a workpiece 23 between spindles 2a, 3a, the lathe, for instance, self holds the motor 5 while applies predetermined torque T2 to the motor 6. Further the lathe, in that condition, releases the motor 5 from its self holding and applies predetermined torque T0 to the motor 5. Consequently, the lathe, starting each spindle 2a, 3a by the respective motors 5, 6, prevents inertia of the spindle 3a, connected to the motor 6, from acting on the workpiece 23. Accordingly, the lathe, when it starts the motors, enables excessive torsional torque to be effectively prevented from acting on the workpiece.

Title: Fluid flow control valve
Inventor: WATABE YOSHIYUKI
IPC: F16K31/02
Filed: 1987-06-23
Abstract: PURPOSE:To enable the fluid flow control valve to quickly cope with transient fluctuations in a primary and a secondary pressure by using a tubular piezo-electric element in which the inside diameter of a tube changes by applying a voltage. CONSTITUTION:A tubular piezo-electric element 1 is installed so as to divide the inside of a valve chest 16 into both sides, namely, an input side and an output side, and the perimeter of a tube is sealed by O-rings 4, etc. so that the gas flow from the primary side to the secondary side is carried out only in the inside of the tubular piezo-electric element 1. When a voltage is applied between electrodes 6, 7, the inside diameter of the tube is reduced. At this time, even if the pressure in the primary side transiently fluctuates, the inside diameter is difficult to be changed because the entire tube is highly rigid. Thus, a valve in which variations in fluid resistance are less relative to the pressure fluctuations in the primary side or the secondary side can be obtained.

Abstract: PROBLEM TO BE SOLVED: To more accurately analyze gas with less amount of specimen by comparing the group of the amount of normalization change of known gas prepared for a database with that of the amount of normalization change obtained by an operation means. SOLUTION: When a test gas is driven from a port 104 while clean air is allowed to flow steadily from air supply equipment 101, adsorption of a sample gas molecule to a gas adsorption film 106 of a crystal oscillator 105 is started. At this time, the change with time in the amount of adsorption of a test gas is converted to the piezoelectric response of the crystal oscillator 105, so that the change in the amount of adsorption with time can be monitored by measuring the oscillation frequency of an oscillation circuit 107 by a frequency counter 109.  A computer 110 tracks the change in the oscillation frequency of the oscillation circuit 107 measured by a frequency counter 109, and compares the group of the normalization change of known gas prepared for a database with that of the amount of normalization change obtained by an operation means according to the change in the oscillation frequency of the crystal oscillator 105, thus identification of the kind of gas flowing in a measurement cell 103 and determination of the concentration can be done.

Abstract: PURPOSE:To uniformalize the distribution in an axial direction of the strength Bg of a magnetic field in a magnetic gap part by providing a soft magnetic material layer in the part facing to the magnetic gap part of a ring shaped magnet. CONSTITUTION:The soft magnetic material layer 5 is provided at the outer surface of a ring magnet 1. In such a case, extremely thin sheet steel is employed as the material, and a radial oriented sintered magnet of neodymium iron boron system is used as the ring magnet, and an iron and steel material is used for a center pole 2 and a yoke 3. Also, a force received by a voice coil when a signal current flows in the voice coil shows the sum of the force applied to each wire composing the voice coil, therefore, the strength Bg traversing the whole voice coil becomes effective. In other words, the magnitude of the whole strength Bg, not partial strength, in the magnetic gap part is important. Therefore, the flux quantity of the magnetic gap part is also important in addition to the uniformity of the distribution of the strength Bg in such sense.

Abstract: PROBLEM TO BE SOLVED: To provide a gas sensor, having a structure which hardly generates welding failures even if extremely severe dimensional control is applied to a cylindrical part in a gas sensor, wherein a casing is constituted as one containing two or more cylindrical bonded by welding. SOLUTION: In a gas sensor 1, two cylindrical parts arranged in a shape generating an axially superposed part in a casing 10 covering a detection element 2, for example, among a protector 17 (outside member) and the protector mounting part 9a (inside member) of a main metal fitting 9, a reduced diameter part 81 in the peripheral direction is formed in the outside member 11 by caulking and a welding part 83 in a peripheral direction is further formed in the reduced diameter part 81, to be bonded to the inside member 9a. By forming this reduced diameter part 81, the gap quantity between the outside member 11 and the inside member 9a at a welding part forming position to enhance adhesiveness and welding failures is hard to generate.  Since good welded and bonded state is obtained even if diameter difference control of the outside and inside members is not severaly performed, the production efficiency and yield of a gas sensor are improved.
